- added VDI support for VirtualBox
  * support format="vdi" in the kiwi type specification
- fixed kiwi --init-cache to find the required typeinfo
- fixed openSUSE 13.1 boot descriptions
  * the default repo setup pointed to 12.3, but should point to 13.1
    This is just for completeness and does not hurt because the repo
    setup for the boot image is inherited by the repo setup from the
    system image. But for standalone boot image builds it's corrected
    now

- arm: fixed openSUSE 13.1 JeOS motd file
  * printed some old information about 12.3
- fixed cloneImage function
  * if there are symlinks pointing to a relative destination
    we fixup the link still pointing to the right location
    with regards to the new origen of the cloned description
- fixed temporary setup of DNS/proxy if cache is used
  * the code returned before we could copy the appropriate files
    from the host to the chroot tree if in cache mode
- added missing gfxmenu module for grub2
  * This prevents the default boot screen to show a broken menu
